For the publication, the plasmid should be drawn as EPS format. i’d like to ask which kind of software usually is used for this purpose? Thanks in advance. You can export vector map from Vector NTI to adobe illustrator, the most sophisticated vector graphics editor. hi friends, I am new to R.I would like to know R-PLUS.Does any know where can I get the free training for R-PLUS. Regards, Peng. Try SnapGene Viewer: http://www.snapgene.com/products/snapgene_viewer/ It’s free, and you can export the plasmid maps in many different formats. Just get random sequence from anywhere (even create it yourself by using repeats) make sure that it is roughly the right size. Add your genes of interest/restriction sites, select them and then add them as features or use the restriction site tool to highlight the RE sites then draw the map… Source.
